The BHW wire cleaning system
is used in the most demanding
applications, allowing
the highest cleaning speed, with all
carbon steel wires (including 0.85%C),
mechanically descaled or acid cleaned,
bare or pre-coated, drawn with calcium or
sodium lubricants.
The BHW system is particularly
recommended for cleaning applications
in which a conventional process is
inappropriate, especially with wires drawn
in severe conditions resulting in increased
heat and burnt lubricant tightly bound to
the wire surface and embedded in micro
cavities.
The BHW system incorporates new
technology which enables normal
plant water to be converted into the
most unique “micro-abrading liquid”
agent used for cleaning of drawn
wire, in-line, at high speed, at
virtually zero energy consumption,
providing extra-clean wire.
Basically, it is a sensitive multi-layer
displace/fine scrub/flush cleaning
system, benefiting from water
immersed high density ultra-fine bristles
performing as porous long-life abrading
pads that smoothly impact wire surface
separating lubricant residue from base
material, washing away dispersed
contaminants by moving wire, exiting
the unit very clean of white-metal
appearance.
At exit, the system can be fitted with the
PWC (Pressure Wet Cleaning) unit for
complete removal of residual moisture
film, providing wire polishing for
reflective appearance.
The BHW system provides the
ultimate combination of simplicity
and effectiveness: Acid-free,
caustic-free, without ultrasonic, without
chemicals. Economical and
environmentally friendly, the system
provides significant energy and process
savings in production of clean H/C and
L/C wires.
The BHW system cleans drawn
wire from lubricant residue in
applications prior to heat treatment
or coating, including galvanising,
annealing, patenting, plating, welding
(chain, mesh), painting, plastic coating, Al
or Cu cladding, etc. In a typical application,
the 2.6mm (0.102") drawn wire is cleaned
in-line at 12m/s (2,400ft/min) with 3 to
5 x BHW units, obtaining a very clean
wire, enabling direct galvanising or other
metallic or plastic coatings.
